To be honest, I was a bit skeptic at first. We have grommet curtains, so I wasnt sure it would work for us. I decided to take the gamble. Installing the Bots themselves was no problem. Very easy to install and the app was working very good. Calibration was done in a few clicks.
The challenge for us was to make the grommets work so that they would expand evenly, and not get stuck. Included in the box is some plastic stuff for that, but that didnt fit between my curtains and the ceiling. Also, I didnt like how they looked. So I decided to drill small holes in the upper back of the rings (invisible there), and to pull a fishing wire of 1mm through it and fix the rings with small steel wire clamps (for 1,5mm). See last picture. This was a lot of (precise) work, but the result is very satisfying. I was a bit worried about the strength of the Bots since one has to pull the curtain for 3,5mtr, but the Bot is able to do it. Very impressed by the strength and the amount of grip the Bot has.
So I would definitely recommend these Bots, I dont see them, and they do the job perfectly.
2 suggestions: 1. make WiFi available on these things because I dont understand why I should buy a Hub to make voice control work. 2. Make the included charging wire 1mtr longer; almost everyone has the wall outlets at floor level and the Bots near the ceiling. So usually that is 2,5 - 3 mtr. Adding a charger cable of 2 mtr makes no sense.
But lets end positive, very surprised and impressed how these Bots work, thumbs up!!
